WiBuntu is an Open source, Operating System based on Ubuntu.
WiBuntu is a Operating System based on the Linux Operating System, Ubuntu. WiBuntu OS focuses on Security, Simplicity, Familiarity and Usability. Our goal is to make Linux a more awesome Operating System than currently is using the best, most useful programs that everyone wants but not the things you do not need and we also thrive in giving you more choice and piece of mind by giving you all the desktops for Ubuntu that co-operate with each other rather than breaking each other. Right now, Linux mostly consists of features that make it very hard to be infected by viruses.
The goal of this project is developing completly free linux environment for Siemens SX1 mobile phone and for any smartphone in the future. Our targets are small size and fast speed.

Alternative operating system for x86 computers
Visopsys is an alternative operating system for PC compatible computers. In development since 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, pre-emptive multitasking, and virtual memory. Though it attempts to be compatible in a number of ways, Visopsys is not a clone of any other operating system. You can demo the distribution from a “live” CD/DVD or floppy disk
